The copper and silver containing (Cu_1−xAg_x)₇SiS₅I mixed crystals with argyrodite structure have been grown by direct solidification using the Bridgman-Stockbarger technique. Measurements of electrical conductivity of mixed crystals by means of impedance spectroscopy were carried out in the frequency range from 2 × 10¹ Hz to 2 × 10⁶ Hz and temperature range 292–378 K. Frequency dependences of total electrical conductivity were studied, Nyquist plots were constructed and analysed. The influence of Cu⁺ → Ag⁺ cation substitution on the total electrical conductivity, on the electronic and ionic components of the electrical conductivity as well as on their activation energies for (Cu_1−xAg_x)₇SiS₅I mixed crystals was investigated.
